Storm Watch Updates


Stormwatch graphicLast updated February 18, 2024

With the ground already saturated from previous storms, the community is encouraged to sign-up for emergency alerts, pick up sandbags, and prepare for the storms in advance. The City will continue to monitor forecasts and conditions, and staff are ready to respond should conditions change.

Heavy Rainfall forecasted the week of February 18, 2024

The National Weather Service issued a flood watch for the entire Bay Area and Central Coast. The current weather system has brought moderate to major impacts persisting into Wednesday. Flooding and rain are the primary concern, with strong gusty winds and hazardous beach and marine conditions. There’s an increased risk of flooding due to excessive rainfall with impacts to creeks, streams, roadways in urban areas and shallow landslides (e.g. rocks or debris on the roadways.)

What you can do

Monitoring Storm Drains: 

Storm drains have limited capacity and flooding may occur in low lying areas. Since Public Works crews may be delayed in responding to reports of flooding, based on the severity of the storm, residents can help by:

  • Checking drainage systems including gutters and removing debris as necessary.
  • Using sandbags and plastic sheeting to protect flood-prone entrances to homes.
  • Ensure that garden waste is not blocking storm drains.

Sandbags

Union City residents and businesses may pick up a maximum of 5 sandbags (per household/business) if needed, while supplies last.  Bags can be found at the Public Works Corporation Yard located at 37650 7th Street. Sandbags can be picked up at anytime.

Safe Driving

Driving slowly and carefully, particularly where water has accumulated on roadways.  Never drive into a large body of standing water.
